This is a Rolex Oyster Bubbleback from the 1930s, an exceedingly rare 1st model featuring a silver two-tone sector dial. It boasts an early four-piece waterproof case construction, consisting of a bezel, middle case, case back, and movement holder. The watch is equipped with the historically significant self-winding Caliber 520 movement, engraved with operational instructions, making it a highly valuable and iconic piece in Rolex's history.
The dial is a stunning two-tone sector design, characteristic of the era, with beautifully aged patina that enhances its vintage appeal. This particular watch was sold by Bucherer, a renowned Swiss jeweler with a long-standing partnership with Rolex. Notably, Bucherer has recently gained attention for its acquisition by Rolex.
Included is a Gay Frères bamboo bracelet (wrist size: 18.5 cm), further enhancing the rarity and charm of this exceptional collector’s item.
